The previous organization of the Attributes section of the manual was like
Attributes
Function Attributes
Common Function Attributes
+ various subsections by target
Variable Attributes
Common Variable Attributes
+ various subsections by target
Type Attributes
likewise
Label Attributes
Enumerator Attributes
Statement Attributes
GNU Attribute Syntax
There was a bunch of introductory text duplicated at the top of the
sections for each kind of attribute, and many attributes were listed
in multiple places -- particularly linker-related attributes like
"section" that apply to both functions and variables with the same
semantics.
The material has been reorganized by merging the corresponding
sections for each kind of attribute:
Attributes
Common Attributes
Target-Specific Attributes
+ various subsections by target
GNU Attribute Syntax
Most of the previous boilerplate introductory text for each subsection
has been discarded since it's been replaced by a general introduction
in the top-level Attributes section in a previous patch of this
series. The duplicate entries for different kinds of attributes of
the same name have been merged and in some cases I reworded things to
provide explicit context about what entities the attribute applies to.

The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
